Neptune is the eighth and farthest planet from the Sun in our Solar System. Named after the Roman god of the sea, it is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 Earth masses and not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth-Sun distance. Its astronomical and astrological symbol is , a stylized version of the god Neptune's trident.

It is an 'ice giant' and has 13 known moons, including Triton, Proteus and Nereid.

It is the ruler of Pisces, the third of the three Water Signs.

Neptune symbolizes our ideals and shows us where we yearn for perfection and merging. Neptune heightens our perceptions, giving us the capactiy for compassion and imagination. If Neptune is strong in the birth-chart, the individual will be highly creative, with a potential for self-sacrifice. Negatively, Neptune can lead an individual into deceptions and hypersensitivity.

Neptune is connected with our fantasies, with our dream world and therefore with drugs and alcohol, the theatre, television, films and religion. Neptune is all that is mysterious in life. This planet can dissolve our reality and replace it with another taking us towards dissolution or allowing us to contact higher realms.

The sign placement of Neptune will apply to all those people born within the same thirteen-year period, as this is the time it takes of Neptune to transit through the whole of one sign. Therefore, it is the house placement and house relationships of Neptune and its aspects to the planets that make it significant for the individual.
